Problems solved by technology
As a tool for hanging heavy objects, the sling is conducive to the lifting and lowering of the heavy objects and improves the transportation speed, but it brings some problems: acceleration, deceleration and external disturbances will cause the heavy objects to swing, which may cause problems during transportation. Heavy objects collide with other equipment, causing unnecessary losses
[0004] There are still many imperfections in the traditional crane control system: it often only depends on the lifting of heavy objects to avoid obstacles, so that the transportation process consumes too much energy; it is difficult to run multiple transportation directions at the same time, which greatly increases the transportation time; the transportation process is difficult Inhibit the swing of heavy objects, increasing the unsafe factors in the transportation process

Embodiment Construction
[0014] First, various equipment and items (including heavy objects to be transported) located in the operating space of the crane are used as obstacles, and the information of these obstacles is input and stored in the computer. The computer automatically removes the heavy objects to be transported from obstacles, and plans an optimal running route based on information such as the position of other obstacles, as well as the current position and target position of the heavy objects. Through the control algorithm inside the computer, the heavy object can track the planned path to achieve the purpose of transportation in the shortest time and the lowest energy consumption, and realize the precise anti-swing and positioning control of the heavy object during transportation. When the transportation task is completed, the computer automatically regards the heavy object as an obstacle and saves information such as its position.

A full-automatic control system for crane is composed of control panel, driver, crane system, computer for planning and controlling the path of crane, weight height sensor for measuring the height and lifting speed of weight, position sensor for measuring the position and speed of crane, and angle measuring unit for measuring 2D swinging angle and angle speed.
Description
technical field [0001] The invention relates to a full-automatic control system of a crane, especially an automatic control system for all-round heavy object transportation. Background technique [0002] As a heavy transport tool, cranes have been widely used in workshops, docks, warehouses, construction sites and other places. As a tool for hanging heavy objects, the sling is conducive to the lifting and lowering of the heavy objects and improves the transportation speed, but it brings some problems: acceleration, deceleration and external disturbances will cause the heavy objects to swing, which may cause problems during transportation. Heavy objects collide with other equipment, causing unnecessary losses. This requires the operator to have quite skilled work experience to reduce the swing of the heavy object during transportation, and at the same time, there must be a worker at the target position to artificially eliminate the swing and place the heavy object at the des...
